You're not far off. The image is part of some sort of desktop background package. Not sure if it's something from Apple but this image is called "Glacier National Park". If you're interested, I could snag it and upload the whole thing. It's 88KB :)

I tried installing more VRAM to see if it made any difference. Indeed, the noise mostly went away if I chose a high resolution and thousands of colors. When switching to a mode for playing games like Marathon or Dark Forces, the noise was very heavy. You, sir, nailed it. As you suggested, I...

HFS (Mac OS Standard) was supported with read/write until some version of Snow Leopard. HFS+ (Mac OS Extended) appears to still be supported by MacOS as of now. I can mount and edit the HFS+ image completely normally and with only first-party software and I'm using Monterey. It's possible that...

In fact, if you change the name of the file you create in my step-by-step (the blank image) from "HD40_512 Shared.img" to "HD40_512 Share.hda" the BlueSCSI and OS 8 don't know the difference. The only reason for naming it .img is easy compatibility with a modern Mac's first-party software. The...

Nearly every (if not every) guide that I see pertaining to BlueSCSI advised that I use a Classic Mac emulator to set up the device. As I intend to share the BlueSCSI as a gift to somebody that isn't as computer savvy as to know how to use Cmd+I to hide or unhide extensions, navigate a file path...

Thanks for helping to revive another old clunker. Now how to revise titles as "resolved".

You guys did it! I was able to give somebody a 1994 Christmas today. The Quadra was recapped, a few IC's repaired, the shell was bleached in hot peroxide and brand new feet attached. The only flaw is a bit of snowy pixels that will be fixed thanks to lobust and AwkwardPotato pointing out how...

Power supplies do resonate, though. I don't suppose there's any way to run it with the power supply disconnected? Haha. I'll come back here when I begin to trace my G5 issues to share whatever I find.

You know I have a similar issue with many derelict or senile computers. I can hear the sound you’re describing. How many moving parts are left in your G4? Ah, just the fan, right? Therefore… My theory is that the loose bearings/bushings in an old fan (or dry bearings, since gravity likes to...

Excellent. Then I will make a few archives of the HDD for safe keeping! The second part is kinda just a dumb idea for no real reason. Imagine you have a Mac that shipped with OS 8. Now you upgrade that system to OS 9. All of your games and settings and files etc. from OS 8 are now in an install...

Only thing to add for now is how to backup or upgrade the current system install on another Mac. The Q610 is running OS 8. I'd like to firstly back this up to the BlueSCSI. As far as I've been able to find, this involves simply creating a blank image on the SD card and then dragging and...

@AwkwardPotato I have to say this is an impressive write-up. You do this for free? Now I can wrap my head around what is going on here. Since you mentioned it, I poked around RC6 and was shocked. The pins all have continuity to different places such as the DAC, at least one goes to the VRAM...

In case it helps: My Quadra with LC chip, AT&T RAMDAC and ethernet has no U3. The AT&T chip is identical to MrFarenheit's. A listing I saw for a Centris 610 board shows it has an RC 25M chip, Apple RAMDAC, ethernet and no U3.

As for the setting, I don’t see anything that mentions auto-configuration if any kind. They really make no mention of refresh etc besides just an info pane that says what it currently being displayed. I will clean the port and will actually check circuits to see that everything is going where...

Previous thread details my path to resurrecting a stored Quadra with leaked caps but intact battery. It now boots perfectly, reliably, and all of the inputs so far (ADB, External and Internal SCSI, Floppy) seem to work without fault. I've been playing all of the games that are on it and it's...

Correction: the chip NEXT TO the RAMDAC is a SCSI controller heh my mistake. So I look forward to any info on the RAMDAC. I did a quick tracing and the DAC and the small IC's below it seem to at least be attached but I fear what you said about it possibly being borked internally. This repair is...

If you happen to have the pinout, it can only help at this point. I do have other monitors but they will be LCD and I know those are picky about resolution and sync but I will try. If this CRT works fine with all my other computers, does that narrow it to the motherboard as the issue? This...

VICTORY! Not only did it run just fine, it even booted from the old HDD. Thing was stuck and needed a bump against the desk to unstick it but it was enough to get it spinning. I was utterly shocked when I saw the OS 8 boot screen. Hasn't booted in seven years. It was also able to boot from...

Well I learned a lot from you guys today. Reading that post kind of clears up that the IOSB is important. It's no wonder none of the SCSI ports try to access data at all. It is also helpful to find that there are automatic terminators so you can run with no internal cable connected and boot...

The first part is good. The second part I don't like so much. I suppose there'd be no harm in just clipping the parts of the NAND chip that go nowhere, eh? Does anybody know what the U46 NAND does or what a NAND IC like this normally would do? Do you think "IOSB" has to do with SCSI...
